Table 2. Comparison of nucleotide (nt) and amino acid (aa) sequences of the surface glycoprotein (G) gene of Japanese 2015 bovine ephemeral fever virus (BEFV) with other East Asian BEFVs.

	nt sequence identity (%)	aa sequence identity (%)
Taiwanese isolates (regarded as exotics) in 2013–2014	99.7–99.8	99.7–99.8
Chinese isolates in 2011–2012	98.9–99.1	99.0–99.7
Taiwanese isolates in 1984–2013	96.2–97.0	98.2–99.5
Japanese isolates in 1988–2012 a)	96.3–96.8	98.7–99.3
Chinese isolate in 2002	96.7	99.2
Chinese isolate in 1976	96.2	98.2
YHL isolate a)	95.7	98.5

a) Shorter length of the G gene, 1,821 nt and 607 deduced aa sequences, were used for the comparison.
